There should be a sort of grab ledge along the left side of the room (on a metallic path); the grab ledge should be at the top of that path. Grab on to it and ride it until it comes to a stop, be careful of a couple of wave of a few flies along the way.After the grab ledge stops moving, jump to the platform that's a bit above and across from you. Follow the morphball tunnel to its end, letting you out close to the terminal.

I got stuck in this room the first time as well. I discovered that grab ledge along the left wall by accident while I was messing around in the room.
